Ok, sorry, by "menu" I meant menu entry.
A shortcut doesn't require you to enter the menu at all. That's what makes it a shortcut.
There are already shortcuts for toggle raw, toggle overrides, and on some cameras, use the zoom lever or buttons for MF. That covers about half of what you listed in your first post. There is also Ev compensation.
Cameras that don't have an Av mode in the canon firmware generally don't have an adjustable aperture, so that doesn't need a shortcut. I guess you could have a force ND shortcut for those cameras.
That leaves shutter speed and ISO.
In the user menu, if you set shutter override type to Ev step, you only have to touch factor to turn it on or off (or you can toggle overrides completely) Similarly for Sv, setting factor to 100 should be good enough (although annoying that you can't set to 80). Alternately, you could use 10 and use the zoom level to adjust the increment as needed.
If I was going to re-work this, I'd do it something like the canon +/- button. One button would cycle through a set of options (Av, Tv, MF distance, Sv etc) and the left/right, up/down or jogdial would adjust. Or you can group them (as canon does on cameras with a jogdial) so Av and Tv appear together and you use up/down to adjust one and left/right (or jogdail) to adjust the other.
Finally, the eventual goal should be to allow users to bind any key to do any action they want
